Camfil Replacement Filters for AHU – AHU Air Filter Replacement Vietnam

Camfil Replacement Filters for AHU provide replacement filtration solutions for air handling units used in commercial buildings, factories, hospitals, pharmaceutical plants, food production, electronics manufacturing, semiconductor facilities, data centers, laboratories, cleanrooms and other HVAC applications.

An AHU may contain several filtration stages rather than only one filter. Depending on the system design, replacement filters may include:

• Coarse prefilters.
• Panel filters.
• Pleated filters.
• Bag or pocket filters.
• Fine ePM1 filters.
• Compact filters.
• V-Bank filters.
• Activated carbon filters.
• Molecular filters.
• EPA filters.
• HEPA H13 or H14 filters where required.

Replacing an AHU filter correctly requires more than matching the external dimensions. The replacement should also be evaluated according to filtration efficiency, applicable standard, airflow, initial pressure drop, operating resistance, frame construction, filter depth, gasket or seal, media and application.

VIETPHAT supports customers requiring Camfil Replacement Filters for AHU in Vietnam with existing-filter identification, technical matching, replacement selection and quotation based on the actual AHU configuration and operating requirements.

What Are Camfil Replacement Filters for AHU?

Camfil Replacement Filters for AHU are air filters selected to replace existing filters installed inside an air handling unit or associated filter bank.

A replacement may be required because the existing filter:

• Has reached its recommended final pressure drop.
• Has accumulated excessive particulate loading.
• Has reached the required maintenance interval.
• Is physically damaged.
• Has a damaged gasket or frame.
• Has reached the end of its useful service life.
• Is no longer available under the original model number.
• Needs to be upgraded to a different efficiency.
• Needs to be replaced with a lower-pressure-drop alternative.

What Is an AHU?

AHU means Air Handling Unit.

An AHU conditions and distributes air through an HVAC system and can contain components such as:

• Outdoor-air intake.
• Mixing section.
• Air filters.
• Cooling coils.
• Heating coils.
• Fans.
• Humidification or dehumidification components.
• Dampers.
• Sound attenuators.
• Heat-recovery components.

Air filtration is one part of the complete AHU system.

Why AHU Filters Need Replacement

Particulate filters capture contaminants as air passes through the media.

As dust accumulates, filter resistance normally increases.

This can lead to:

• Higher differential pressure.
• Greater fan-pressure requirements.
• Reduced airflow where fan capacity is limited.
• Higher fan-energy demand when airflow is maintained.
• Reduced HVAC performance.

Replacement at an appropriate operating point helps maintain the intended balance between filtration performance, airflow and energy consumption.

Camfil Replacement Filter Stages for AHU

AHU Stage	Typical Filter Type	Primary Function
Stage 1	Panel / Pleated Prefilter	Capture coarse particulate contamination
Stage 2	Bag / Pocket Filter	Medium and fine particulate filtration
Stage 2 / Final	Compact / V-Bank Filter	Higher-efficiency ePM filtration
Gas Phase	Activated Carbon / Molecular Filter	Selected gases, VOCs and odors
Critical Final Stage	EPA / HEPA	High-efficiency particulate filtration

The actual number and sequence of stages depends on the AHU and application.

Typical Multi-Stage AHU Filtration

A General Ventilation AHU may use:

Outdoor Air → Prefilter → Fine Filter → Cooling Coil → Fan → Supply Air

A higher-efficiency system may use:

Outdoor Air → Panel Prefilter → ePM1 Bag/Compact Filter → Coil → Fan → Supply Air

A critical clean-air system may use:

Prefilter → ePM1 Filter → AHU → HEPA Final Filter → Controlled Area

These are conceptual arrangements only. The correct filtration sequence should be based on the actual AHU design and required air quality.

Camfil Panel Replacement Filters for AHU

Panel filters are frequently used as the first filtration stage in AHUs.

Relevant Camfil families can include:

• 30/30.
• AeroPleat.
• Dual10.
• EcoPleat.
• Other regional panel-filter configurations.

Panel construction does not define one specific efficiency. Current Camfil panel products cover different ISO 16890 performance levels depending on the model.

Camfil 30/30 Replacement Filters

Camfil 30/30 is commonly used as an upstream particulate filter to help protect downstream filtration and HVAC components.

When replacing an existing 30/30 filter, check:

• Exact product or article number.
• ISO 16890 classification.
• Width.
• Height.
• Depth.
• Design airflow.
• Pressure drop.
• Frame type.

Do not automatically specify every 30/30 filter as “G4.” Current product data should be used because configurations and classifications can differ.

Camfil AeroPleat Replacement Filters

Camfil AeroPleat is another panel-filter family that can be used for prefiltration and General Ventilation applications.

Depending on the current model and market, configurations can differ in:

• Frame material.
• Filter depth.
• Efficiency.
• Media construction.
• Airflow.
• Pressure drop.

The existing label or technical data should therefore be checked before replacement.

Camfil Bag Replacement Filters for AHU

Bag filters, also called pocket filters, are widely used as intermediate or final General Ventilation filters in AHUs.

Camfil's current portfolio identifies bag/pocket filters for HVAC final filtration and as prefilters for HEPA installations.

A major Camfil product family is:

Hi-Flo

Camfil Hi-Flo Replacement Filters

Camfil Hi-Flo uses glass-fibre media with a robust metal header frame in current referenced configurations.

Important characteristics include:

• ISO 16890 efficiencies.
• Low initial pressure drop.
• High dust-holding capacity.
• Multiple pocket configurations.
• Multiple dimensions.
• Long operating life.
• Energy-efficient design.

Hi-Flo Replacement Filter Size

Hi-Flo filters are available in multiple width, height and bag-depth combinations.

A commonly encountered full-module face size is approximately:

592 × 592 mm

but half-size and other configurations are also available.

Bag depth may vary significantly according to the specific product.

Never order an AHU bag filter from the face dimensions alone.

Why Pocket Number Matters

The number of pockets influences:

• Effective media area.
• Air distribution.
• Pressure drop.
• Dust-loading behavior.
• Physical fit inside the AHU.

However, pocket count alone does not define filtration efficiency.

Always verify the ISO 16890 classification.

Camfil Compact Replacement Filters for AHU

Compact filters can provide a large media area in a rigid configuration.

They are useful where the AHU requires:

• Higher airflow.
• Compact installation.
• Higher particulate efficiency.
• Stable construction.
• Low pressure drop.
• Longer operating life.

Relevant Camfil families include products within the Opakfil range.

Camfil Opakfil Replacement Filters

Opakfil compact filters are commonly relevant to AHU replacement applications requiring high-efficiency General Ventilation filtration.

Depending on the current model, the product may provide ISO 16890 ePM performance such as:

• ePM10.
• ePM2.5.
• ePM1.

Exact performance should be taken from the specific Camfil product data rather than inferred from the physical V-Bank construction.

Camfil Opakfil ES Replacement Filters

Opakfil ES is particularly relevant where AHU operators want to combine fine particulate filtration with low pressure drop and energy-efficient operation.

Current product configurations include different ePM1 efficiency levels.

Replacement selection should compare:

• ISO 16890 efficiency.
• Dimensions.
• Rated airflow.
• Initial pressure drop.
• Available installation depth.
• Existing header/frame arrangement.

Camfil V-Bank Replacement Filters for AHU

A V-Bank filter uses multiple filter packs arranged in a V-shaped configuration.

The design can provide a large media area within a compact housing.

Potential advantages include:

• High airflow.
• Large media area.
• Compact depth.
• Controlled pressure drop.
• Rigid construction.

V-Bank describes filter construction, not a filtration class.

A V-Bank filter may be a General Ventilation filter, EPA filter or HEPA filter depending on the tested product.

Camfil HEPA Replacement Filters for AHU

Some AHUs or make-up-air/recirculation systems use EPA or HEPA filtration.

Relevant Camfil products include:

• Absolute V.
• Absolute VGHF.
• Other application-specific Absolute configurations.

Camfil Absolute V Replacement Filters

Camfil Absolute V is designed for extra-high-efficiency final filtration where high airflow and relatively low pressure drop are required.

The current Absolute V family covers:

E10 to H14

with MPPS efficiencies across the family ranging from approximately:

85% to 99.995%

depending on the selected filter class.

Camfil Absolute VGHF for AHU

Absolute VGHF is a compact EPA/HEPA filter with a header frame designed specifically for air-handling units requiring high airflow and low pressure drop.

Current Camfil product information identifies it as a potential solution for upgrading an AHU to higher EPA/HEPA filtration where the system is technically compatible.

However, an AHU should not be upgraded to HEPA simply because the replacement filter fits physically.

Can an Existing AHU Be Upgraded to HEPA?

Potentially, but a technical review is required.

Check:

• Fan static-pressure capability.
• Required airflow.
• HEPA initial pressure drop.
• Expected loaded pressure drop.
• Filter-bank construction.
• Mechanical support.
• Gasket and sealing system.
• Potential bypass leakage.
• Access for filter replacement.
• Integrity-testing requirements.

HEPA retrofit is an engineering change, not simply a filter-size substitution.

Camfil Activated Carbon Replacement Filters for AHU

Where the AHU must control selected gaseous contaminants, odor or VOCs, a gas-phase filtration stage may be installed.

Camfil provides molecular-filtration solutions using activated carbon and other specialized adsorbent media.

These filters perform a different function from particulate filters.

Particulate Filter vs Carbon Filter

Filter Type	Primary Function
Panel Filter	Coarse particulate filtration
Bag Filter	Medium/fine particulate filtration
Compact ePM1 Filter	Fine particulate filtration
HEPA Filter	High-efficiency particulate filtration
Activated Carbon Filter	Selected gases, odors and VOCs
Specialty Molecular Filter	Target-specific gaseous contaminants

Can Carbon Filter Replacement Be Determined by Pressure Drop?

Not reliably.

A particulate filter normally accumulates dust and its pressure drop generally increases.

Activated carbon can become chemically saturated without a comparable increase in pressure drop.

Therefore, molecular-filter replacement should consider:

• Target contaminant.
• Contaminant concentration.
• Adsorbent type.
• Media quantity.
• Operating time.
• Environmental conditions.
• Breakthrough monitoring where appropriate.

How to Identify the Correct Camfil AHU Replacement Filter

The safest approach is to identify the existing filter systematically.

Step 1 – Find the Filter Label

Look for:

• Camfil name.
• Product family.
• Article number.
• Filter class.
• Dimensions.
• Airflow.

Step 2 – Record Actual Dimensions

Measure:

Width × Height × Depth

in millimetres.

Step 3 – Identify the Filtration Standard

Look for:

• ISO 16890.
• EN 1822.
• ISO 29463.
• Legacy EN 779 if the filter is older.

Step 4 – Determine Design Airflow

Record airflow per filter module in m³/h where available.

Step 5 – Record Pressure Drop

Identify initial and recommended final pressure drop where documented.

Step 6 – Check Frame and Seal

Inspect:

• Header frame.
• Box frame.
• Gasket position.
• Gel seal where applicable.
• Mounting clips.
• Filter-bank dimensions.

Nominal Size vs Actual Filter Size

One of the most common AHU replacement mistakes is confusing nominal dimensions with actual dimensions.

For example, filters may use actual dimensions such as:

• 592 mm.
• 595 mm.
• 490 mm.
• 287 mm.

depending on the filter family and installation system.

A difference of only several millimetres can affect sealing and fit.

Always verify actual dimensions before ordering.

Why Filter Dimensions Alone Are Not Enough

Two filters measuring 592 × 592 × 300 mm may have completely different performance.

They can differ in:

• ISO 16890 efficiency.
• EPA/HEPA class.
• Rated airflow.
• Initial pressure drop.
• Media area.
• Dust-holding capacity.
• Frame material.
• Gasket arrangement.
• Energy performance.

Therefore:

Same Size ≠ Same Filter

ISO 16890 for AHU Replacement Filters

For current General Ventilation filter specification, ISO 16890 should normally be used.

The major particulate groups include:

• ISO Coarse.
• ePM10.
• ePM2.5.
• ePM1.

Older AHU documentation may still specify G4, M5, M6, F7, F8 or F9 under the former EN 779 system.

Replacing Legacy G4, F7, F8 or F9 Filters

Older AHUs frequently have specifications using legacy EN 779 classes.

Do not assume an exact universal conversion such as:

F7 = one fixed ePM1 percentage

or:

F9 = one fixed ePM1 percentage.

ISO 16890 uses a different test and classification methodology.

For replacement, review the current manufacturer's tested ISO 16890 data.

EN 1822 and ISO 29463 for HEPA Replacement

EPA, HEPA and ULPA filters use different standards from General Ventilation filters.

Relevant standards include:

• EN 1822.
• ISO 29463.

For example, under EN 1822:

• H13 overall efficiency is at least 99.95% at MPPS.
• H14 overall efficiency is at least 99.995% at MPPS.

Therefore:

ePM1 ≠ H13 ≠ H14

Can an F7 Filter Be Replaced with F9 or Higher ePM1?

Potentially, but the AHU should be checked first.

A higher-efficiency filter can have different resistance characteristics.

Evaluate:

• Existing airflow.
• Existing pressure drop.
• New filter pressure drop.
• Fan available static pressure.
• Cooling and heating coil performance.
• Required ventilation rate.

Can a Bag Filter Be Replaced with a Compact Filter?

Potentially, if the AHU and filter bank are compatible.

Compare:

• Face dimensions.
• Installation depth.
• Header design.
• Efficiency.
• Airflow.
• Initial pressure drop.
• Loaded pressure drop.
• Mechanical support.

A compact filter may provide advantages in certain applications, but it should not be substituted solely because it fits the opening.

Camfil Replacement Filters for AHU in Commercial Buildings

Commercial AHUs may use Camfil replacement filters in:

• Office buildings.
• Hotels.
• Shopping centers.
• Airports.
• Schools.
• Retail facilities.
• Public buildings.

Common replacement requirements include panel prefilters, bag filters and compact ePM filters.

Camfil Replacement Filters for Hospital AHUs

Hospital AHUs can require different filtration stages according to the served space.

A conceptual arrangement may include:

Prefilter → ePM1 Filter → HEPA where required

HEPA is not automatically required in every hospital AHU or room.

Filter replacement should follow the HVAC and infection-control requirements applicable to the specific area.

Camfil Replacement Filters for Pharmaceutical AHUs

Pharmaceutical HVAC systems may use:

• Prefilters.
• Fine ePM1 filters.
• H13/H14 HEPA filters.
• Specialized exhaust filters.

Replacement work must also consider contamination control, room pressure, airflow and qualification requirements.

Replacing the filter alone does not establish GMP compliance.

Camfil Replacement Filters for Cleanroom AHUs

Cleanroom AHUs frequently use upstream filters to protect terminal HEPA or ULPA filters.

A conceptual sequence may be:

Prefilter → ePM1 Filter → AHU → Terminal HEPA/ULPA

Cleanroom classification under ISO 14644 is based on room/system performance and is not determined solely by the replacement filter class.

Camfil Replacement Filters for Electronics Factories

Electronics manufacturing can require:

• High-efficiency particulate filtration.
• Low pressure drop.
• Stable airflow.
• HEPA/ULPA where required.
• Molecular filtration where AMC control is required.

The particulate and molecular filtration requirements should be evaluated separately.

Camfil Replacement Filters for Semiconductor AHUs

Semiconductor facilities require clear separation between particulate and gaseous contamination control.

Filter	Main Function
ePM1	Fine particulate filtration
HEPA	High-efficiency particulate filtration
ULPA	Ultra-high-efficiency particulate filtration
Molecular Filter	Target-specific AMC control

HEPA or ULPA filtration does not replace molecular filtration for gaseous AMC.

Camfil Replacement Filters for Food Factory AHUs

Food-production AHUs may use different filters according to hygiene zoning and product exposure.

Potential replacement stages include:

• Panel prefilters.
• Bag filters.
• ePM1 compact filters.
• HEPA filters where process risk requires them.

There is no universal requirement that every food factory AHU use HEPA filtration.

Camfil Replacement Filters for Data Center AHUs

Data-center AHU replacement should consider both contamination control and cooling-airflow requirements.

Important parameters include:

• Outdoor particulate concentration.
• Economizer operation.
• Design airflow.
• Filter pressure drop.
• Fan energy.
• Gas-phase corrosion risk.

Where corrosive gases are present, an appropriate molecular filtration stage may be required in addition to particulate filtration.

Camfil Replacement Filters for Manufacturing AHUs

Factory AHUs may use Camfil filters to serve:

• Production rooms.
• Packaging areas.
• Control rooms.
• Quality-control areas.
• Equipment rooms.
• General manufacturing spaces.

AHU filters should not be confused with dedicated process dust collectors. High dust-generation processes may require source-capture systems such as cartridge collectors, baghouses or other engineered extraction systems.

Check the AHU Filter Bank Before Replacement

Before installing new filters, inspect:

• Filter-bank frame.
• Holding clips.
• Gaskets.
• Corrosion.
• Mechanical damage.
• Debris accumulation.
• Bypass gaps.
• Access doors.

A high-efficiency filter cannot perform as intended if significant unfiltered air bypasses the media through gaps around the filter.

Filter Bypass Leakage

Bypass occurs when air travels around rather than through the filter media.

Possible causes include:

• Incorrect dimensions.
• Damaged gasket.
• Insufficient compression.
• Deformed filter bank.
• Incorrect installation.
• Missing retaining clips.

Bypass control becomes increasingly important as filtration efficiency increases.

AHU Filter Differential Pressure

Differential pressure is one of the most useful parameters for particulate-filter maintenance.

It can help indicate:

• Filter loading.
• Increasing airflow resistance.
• Potential replacement timing.
• Abnormal airflow conditions.

Where practical, AHUs should use differential-pressure monitoring rather than relying only on arbitrary calendar replacement intervals.

How Often Should Camfil AHU Filters Be Replaced?

There is no universal replacement interval.

Service life depends on:

• Outdoor-air pollution.
• Indoor recirculated contamination.
• Operating hours.
• Airflow.
• Filter efficiency.
• Media area.
• Dust-holding capacity.
• Upstream filtration.
• Application hygiene requirements.

Manufacturer guidance, pressure-drop monitoring and site conditions should be considered together.

Can Camfil AHU Filters Be Washed?

Only filters explicitly designed and documented as washable should be washed.

Conventional:

• Bag filters.
• Fine filters.
• Compact filters.
• HEPA filters.
• ULPA filters.

are generally disposable.

Washing can damage the media, pleat geometry, separators, sealant or filtration performance.

Can AHU Filters Be Cleaned with Compressed Air?

Compressed-air cleaning should not be treated as a general regeneration method for disposable fine or high-efficiency HVAC filters.

It can damage filter media and does not reliably restore original tested performance.

Replacing Camfil Filters with Another Brand

If brand substitution is permitted, a technically compatible filter can be evaluated.

The comparison should include:

• Efficiency.
• Applicable standard.
• Actual dimensions.
• Rated airflow.
• Initial pressure drop.
• Operating pressure-drop characteristics.
• Media area.
• Frame construction.
• Gasket.
• Service life.

“Same size” or “same legacy class” alone does not establish equivalence.

Replacing Another Brand with Camfil

A Camfil filter can also be evaluated as a replacement for another manufacturer where the technical requirements and AHU construction are compatible.

Useful information includes:

• Existing brand.
• Existing part number.
• Existing datasheet.
• Filter photographs.
• Actual dimensions.
• Efficiency.
• Airflow.
• Pressure drop.
• Application.

Replacing a Discontinued Camfil Filter

If an older Camfil model is no longer available, replacement identification can often begin from:

• Old Camfil part number.
• Product label.
• Old technical datasheet.
• Purchase records.
• AHU schedule.
• Photographs.
• Actual dimensions.

The replacement should be selected according to current technical performance rather than relying only on a historical product name.

How to Photograph an Existing AHU Filter for Identification

For remote identification, provide clear photos of:

• Complete filter front.
• Complete filter side.
• Product label.
• Header/frame.
• Gasket.
• Filter bank inside the AHU.
• Measurement of width.
• Measurement of height.
• Measurement of depth.

This can significantly improve replacement matching when the original part number is unavailable.

Camfil AHU Filter Replacement and Energy Efficiency

Air-filter replacement can affect AHU energy performance because filters create resistance that the fan must overcome.

When evaluating replacement filters, consider:

• Initial pressure drop.
• Average operating pressure drop.
• Dust-loading behavior.
• Service life.
• Replacement frequency.
• Fan energy.

The lowest purchase-price filter is not necessarily the lowest lifecycle-cost solution.

Total Cost of Ownership for AHU Replacement Filters

A lifecycle evaluation can include:

• Filter purchase price.
• Fan-energy cost.
• Service life.
• Maintenance labor.
• Replacement frequency.
• Disposal.
• Impact on downstream filters.
• Impact on coils and system cleanliness.

How to Select Camfil Replacement Filters for AHU

1. Identify the Existing Filter

Record manufacturer, model and article number.
